Product DescriptionA boom is indispensable for recording with the camera positioned outside the center of the tripod. Especially for top down, macro, food or repro-photography, the boom is unavoidable. What sets the SIRUI HA-77 apart is its telescopic function. The Sirui HA-77 Horizontal Arm can be extended to 77cm, making it extremely flexible. With 360° rotation and 90° tilt to any side, almost any position can be obtained.
